Approximately 5% of children and 1–10% of adults who present to audiology departments with complaints of significant listening difficulties in noise or in group conversations have normal pure-tone thresholds.1,2 In a proportion of these patients, their listening symptoms are attributed to functional deficits in sound processing within the extended central auditory nervous system.3 This clinical presentation is categorized as auditory processing disorder (APD, category H93.25 in ICD-10).4 This clinical presentation has attracted considerable debate that is summarized to some extent in several consensus statements from professional audiological organizations.5–9 However, there is no international consensus on what constitutes APD as yet, nor is there explicit agreement on diagnostic criteria for this clinical entity.
Auditory Processing Disorder

The diagnosis of (central) auditory processing disorder [(C)APD] is made when a patient has difficulty hearing that cannot be accounted for by peripheral hearing loss or other cognitive deficits. Patients with APD typically have difficulty in sound localisation, auditory discrimination (i.e. hearing in background noise), pattern recognition, temporal aspects of audition and auditory performance in competing acoustic signals. This causes functional impairments in listening, learning and spoken language comprehension and development.1

Approximately 5% of children and 1–10% of adults who present to audiology departments with complaints of significant listening difficulties in noise or in group conversations have normal pure-tone thresholds. In a proportion of these patients, listening symptoms are attributed to functional deficits in sound processing within the extended central auditory nervous system. This clinical presentation is categorised as an auditory processing disorder (APD). APD is a common type of hearing impairment that remains under recognised, despite its high burden on communication, social, and emotional aspects of life. This clinical presentation has attracted considerable debate. A recent European consensus proposes that APD is diagnosed on the basis of the following criteria3: Normal audiometric thresholds in both earsAbnormal performance in at least two validated auditory processing tests that assess different processes in at least one ear, including in a non-speech testPresence of listening difficulties (Table 16.2) and/or risk factors associated with APDNormal non-verbal intelligenceGood ability to follow test instructions
Evaluation of a game-based hearing screening program for identifying hearing loss in primary school-aged children

Studies of primary school aged children in Poland, South Africa, the United Kingdom and the United States suggest that 2–16% of children in the age range of 5–13 years have an unidentified hearing loss (Bess, Dodd-Murphy, and Parker 1998; Niskar et al. 1998; Bamford et al. 2007; Mahomed-Asmail, Swanepoel, and Eikelboom 2016; Skarżyński et al. 2020). Prevalence data from three Australian studies analysed in a systematic review estimated the rate of all hearing impairment in schools to be between 3.2% and 12.8% (Choi, Kei, and Wilson 2017). CHLs account for most of the identified hearing loss, with between 2.6% and 7.1% of children tested presenting with this type, compared to 0.1–1.19% with SNHL and 0.1–4.0% mixed hearing losses (MHL) (Choi, Kei, and Wilson 2017). While estimations of auditory processing disorder (APD) prevalence lie between 2% and 5% (Chermak and Musiek 1997; Nagao et al. 2016), few studies have examined true prevalence in primary school aged children. A study of 144 primarily normal hearing Indigenous Australian children found a presentation rate of 6.9% among those sampled (Cameron et al. 2014). Another study found that of 183 children referred for testing by parents or teachers due to having difficulty listening in noise, 32 (17.5%) were ultimately found to have a SPD (Dillon et al. 2012). SPD prevalence rates in children with previous episodes of OM are known to be higher than age matched controls; another study found 24% of children (20/82) with a clinical history of OM presented with SPD, compared to 0% (0/36) in a control group (Graydon et al. 2017).
Comparative assessment outcome of the cognitive and developmental traits in adults with listening difficulties

Some adults have difficulties in comprehending and following verbal information in noisy environments despite having normal hearing. The symptoms were termed as auditory processing disorder (APD) for a long time. The clinical features and management approaches for APD abound in literature [1,2] with widespread clinical practice guidelines across countries [3–5]. Recently, some researchers have raised questions regarding the correctness of the definition and terminology of APD [6,7]. Moore [6] recommended that listening difficulties (LiD) are a better terminology than APD. The author argued that APD does not meet the criteria for a disorder and that the associated problems are not confined to the central ‘auditory’ system. In this context, we used the term ‘LiD’ to describe symptoms characterized by normal hearing but difficult listening.
Auditory processing and non-auditory factors associated with hyperacusis in children with auditory processing disorder (APD)

Multidisciplinary evaluation of children with auditory processing disorder has been recommended to identify different co-morbid conditions and facilitate optimal individualised support and to help clinicians and researchers to reach an operational diagnosis of APD [17]. DeBonis [9] recommended the use of the Children’s Communication Checklist-2 (CCC-2) [24] and the Behaviour Rating Inventory of Executive Function (BRIEF) [25] to evaluate language ability and executive function, respectively. The Swanson Nolan and Pelham (SNAP-IV) parental and teacher rating scale, assessing ADHD and oppositional defiant behaviour [26], is also used in APD assessment [10,27]. Anxiety is also common in ADHD and ASD [20] and questionnaires are available to evaluate anxiety in children [28]. In this study, the relationship between hyperacusis, different aspects of auditory processing and multidisciplinary APD evaluation that include anxiety, attention, language and oppositional defiant symptoms in children who failed at least 2 out of 5 diagnostic auditory processing tests from the SCAN-3 test battery [29,30] and diagnosed with APD are evaluated.
